Thank you Ms. Sue for your invauable help! Here is the second part of the letter I need to hand in by tomorrow.

As writeacher is not there, could you please help me check it? Many thanks in advance.

This two-year project will be mainly about a comparative study on biodiversity in water and other waterways in our local areas and English has been chosen as our lingua franca.
2) In particular, your school could help our Italian science teachers build a scientific vocabulary in English to be used when working on the project.
3)This preliminary work will then enable our students to communicate the results of their achievements to the Irish students involved in the Comenius project.
4) We have decided to hold a preliminary meeting in Italy on 27. January and 28. January in order to agree on the objectives and the number of mobilities of both teachers and students which will occur (??) in the course of (during?) the two years.
5) The German school will act as coordinator of the project and so is responsible for drawing up the project itself and sending it to its national agency by 21 February.
6) We, as partners, will have to send a copy of the same project to our local agencies by the same deadline.

1) . . . areas. English has been chosen . . .

2) OK.

3) OK.

4) Drop "which will occur." "During" is better.

5) OK.

6) OK.

Sure, I'd be happy to help you check your letter! Here's a breakdown of each sentence:

1) This two-year project will be mainly about a comparative study on biodiversity in water and other waterways in our local areas and English has been chosen as our lingua franca.

- Sentence looks good! It clearly states the main focus of the project and the language to be used.

2) In particular, your school could help our Italian science teachers build a scientific vocabulary in English to be used when working on the project.

- Sentence is grammatically correct and conveys the intention for the school to provide assistance in building scientific vocabulary in English.

3) This preliminary work will then enable our students to communicate the results of their achievements to the Irish students involved in the Comenius project.

- Sentence is clear and explains how the preliminary work will benefit the students by allowing them to communicate their achievements to the Irish students.

4) We have decided to hold a preliminary meeting in Italy on 27. January and 28. January in order to agree on the objectives and the number of mobilities of both teachers and students which will occur during the course of the two years.

- Sentence is good, but there are a couple of suggestions for improvement:
- Instead of "occur," you could use "take place" for better clarity.
- Instead of "during the course of the two years," you could simply say "during the two-year period."

5) The German school will act as the coordinator of the project and is responsible for drawing up the project itself and sending it to its national agency by 21 February.

- Sentence is correct and provides the necessary information about the German school's responsibility.

6) We, as partners, will have to send a copy of the same project to our local agencies by the same deadline.

- Sentence is clear and accurately states the requirement for partners to send a copy of the project to their respective local agencies by the deadline.

Overall, your letter appears well-written and conveys the necessary information. Good job!

Just a note: It seems like the letter is addressing someone named "Ms. Sue," but in your request, you mentioned that Writeacher is not available. You may want to double-check the name of the person you are addressing in the letter to ensure accuracy.
